Application'filed'llarch21,1932. Serial No. 600,330. 7 f 1 Thisinvention relates to abrading, polishing or like surfacing tools, andhas more particular reference to an improved device for holding sheetsof abrasive, polishing or like material so that the same may beconveniently and effectively employed in abrading, polishing orotherwise finishing surfaces.

An object of the invention is to provide a holder of the above kindwhich is extremely simple and durable in construction and eflicient inuse. a V 7 Another object of the invention is to pro vide a holder ofthe above kind which may be conveniently manipulated by which the sheetof finishing material may be securely held in proper condition for use.and which will permit the ready application or removal of the sheet ofpolishing material for renewal from time to t me as found necessary.Other objects and features .of the invention will become apparent fromthe following description when considered 'in'connection with theaccompanying drawing, in which:

Figure 1 is a perspectiveview'of a tool embodying the present invention.

Figure 2 is a side elevational view thereof! Figure 3 is a transversesection on line 38 ofFigure2;and-

Figure 4 is a perspective View of the'body l'thhh tl" 'd.h d. e OfPt'hetoo W1 t e 8 e8 ampmg 111;: the latter in place between'the'wingsfi} andsaid lower: portions of the members 11.-

grip forming members removed.

Referring more in detail to the drawing,

the tool shown may be convenientlymade of stamped metal and consists ofa body memher 5 formed from a single sheet of metal, centrally foldedupon itself and having its free end portions directed laterally inopposite directions'to form co-planar wings 6.

Disposed against and covering the under surfaces of the wings 6 isabaseplate! hav ng its margin tightly folded over and upon the marginal edgeportions of the wings 6 to securely fasten the base plate 7 to thelatter and to form a support for the sheet of abrad ing, polishing orlike material 8. V

The fold of the sheet from which the body 5 is formed has theintermediate portion thereof cut away'as at 9, and the end portionstates the ready apPlicationof a sheet" 8 to a of the fold which are-leftare given formation to formhingebarrelslO. I

Oppositely facingsubstantially" S-shaped; clamping and handigrip formingmembers 11 are hinged to and arranged at opposite 5 sides of the body 5,the upper "edges" of said members 11 being formed with interfittinghinge barrels l2 to'jreceive a hinge pin 13' which also passes throughthe hinge barrels 10. It will be'seenthatthe upper outwardly ii curvedportions of the members 11 cooperate to form a rounded handgrip; whilethe lower outwardly directed portions of said members 11 arearranged tooverlie the wings 1 6 when the members lllare swung down-' 5 wardly tothe full line operative position of Figures 1 to 3 inclusive Thus,.whenthe sheet of abrading, polishing'or likematerial 1 8 is arranged againstthe under side of the" aplate 7 and has its side edge portions folded lover upon the wings 6, the lower portions of the members 11 will tightlygrip said folded over edges of the sheet 8 with a force propor-' tionalto the tightness with which the members 11 are gripped at their upperportions;

In other Words,- when the upper portions of the members 11 are grippedtightly, said members are forced toswing downwardly and inwardly'towardeach otherlwith their! 89 lower portions engaging t-hefoldedover edgeportions of the sheet 8 and securely clamp-" The hinge pin 13has'frictional engagement in the'barrels 12. of the members llr-and oneend of the pin 13 :projjects beyond the! adjacent endofthe body 5Qandisformed with-9 I V V a finger loop or handle 14.) Thus,:by swing-t wardlyand upwardly to release the adjacent edge portion of the-sheet 8, w hilethe other edge portion of thesh eeth8= may be ,releafsedl'f by swingingthe handlepr loop 14 .intheop posite direction. This arrangement.facilithe tool proper. orinstanc'e, assumingithatr a new sheet isbeingapplied; and thatonfe' of the members llhas been raised as indicated fby dotted unegm Figure 1, an 'edge ofthe 40 I ing the tool withoutdeparting from the sheet may be folded-upon the wing 6 at the side ofthe tool where the raised member 11 is located. The handle or loop 14may then be swung in a direction to lower this member 11 which, has beeninitially raised so as to bring it into gripping engagement with thefolded over edge of the sheetS, and to sin1ul-- taneously swing theother member 11 outwardly and upwardly. The folded over edge portion ofthe sheet 8 is thus gripped, and

" the" opposite member ll is raised so that'the other edge portion ofthe sheet 8 may be fol ded conveniently to be subsequently held bymanual movement of the second member 11 downwardly and inwardlytooperative position. The frictional engagement of pin 123 permitsslippageithereof relative to the hinge barrels 12 so that either member11 may "be moved to raisedfor released position while tlie other member'11 remains stationary, said other member 11 being prevented frommovementby its engagement with the base of the tool or theadJacentufOlded over edge of the sheet 8.1 However, when both members 11are brought 1nto gripping engagement with the folded over edges of thesheet 8, they may rubbingfthe surface to be abraded, polished. orOtlIGI'WISB finished with the under surfacebe gripped and movedrelatively toward each other .and relative to the pin, 13 to tightlyhold the sheet 8 in place while the tool is in use. Obviously, atool ofthis kind is used by simply grasping the hand grip 'portionand of thesheet'8. V x

l Vlnle I have shown and described what I bOlIGVQEIt present to be thepreferred embodinientof my invention, it is nevertheless to beunderstood that various changes maybe made in the details and manner'ofconstructf spirit-and scope ofthe invention as claimed.

*IVhat I claim as new is:

1.. A tool of the character described comprising a fiat base having acentral upstand- "mg, body of rib-like form and adapted; to have theopposite edge portions of a sheet'of I rabrading,'polishing or likematerial folded cover and upon opposite side portions thereof,-

andjoppositely facing substantially S-shaped members hinged to the upperedge of said riblike body, said hinged members having up- I per portionscooperating to form a hand grip the opposite side portions ofthebasewhen 7 Y saidbody, and combined hand grip formingand; sheetclampingmembers arranged at pp- .posite sid esjof the bodyandprovi'dedwithi and lower portionsarranged to clamp the folded overedge portions of the sheet upon said members are gripped.

'2. A tool. of the character described com prisinga fiat base having arigid upstanding body in the form of a rib, a hinge pinparallclwvith andournaledgin the upper edge of hinge barrels at their upper edgesfrictionally receiving said hinge pin, said hinge pin having aprojectlng end formed to provlde a handle for manipulating said members.
